To all whom t may concern.'

Be it known that I, WILLIAM J. HILLE, a citizen of the United States,residing at the cit of Philadelphia, in the county of Philade phia andState of Pennsylvania, have invented certain new and useful Im rovementsin Roller-Skates, of which the fo lowing is a specification.

My invention relates to certain improvements in constructive arrangementof a clam ing device for detachably fastening by the s oe-sole theroller skate to the foot-plate thereof.

The principal object of my present invention is to provide a clampingdevice connected with foot-plate of the skate for securin the shoe-solethereto, which is more relia le as well as positive in action, and alsoWhich is differently arranged for use, from constructive arrangements ofsuch devices, as disclosed familiarly in the prior art by U. S. LettersPatent No. 329,239, dated October 27th, 1885, No. 622,838, dated April11th, 1899, and No. 655,673, dated August 7th, 1900, in which thereover,in the present instance are provided slotted guides for movableclamping-bars integrally formed with and de ending from the outer frontportions on botfiJ sides of the skate foot-plate and the clamping-barsextending therethrough controlled by a reversely threaded bolt extendingthrough openings rovided in each of the clamping-bars for tightening andloosening the same with respect to the shoe-sole as Well as in respectto each other.

My invention consists of a shoe-sole clamping device for a roller-skateconstructed and arranged for use in substantially the manner hereinafterdescribed and claimed.

The nature and characteristic main features of my present invention withrespect to the roller-skate will be more fully understood from thefollowing description taken in connection with the accom anying drawin sforming part hereof, in w ichigure 1, is a side elevational view of aroller-skate with a clamping device of the particular features of mypresent invention shown in a plication thereto. Fig. 2, is a front viewo the skate, showing the clamping Specification of Letters Patent.

i device with the threaded bolt in a position for fastening theshoe-sole securely thereto from the foot-plate. Fig. 3, is a perspectiveview of one of the slotted guides formed integral with the foot-plateand depending therefrom; and Fig. 4, 1s a similar view of the dependingrecessed bearing support of the foot-plate for the Unthreaded andrecessed portion of the locking-bolt for the shoe or foot clamping-barsof the skate.

Referring to the drawings A, is the rollerskate of any ordinary wellknown type having a foot-plate a, with the front or toe portion wherethe boot or shoe rests in normal position thereupon, with two integraldepending oblong slotted guides b b1.

c, c1, are two narrow clamping-bars, each having an upturned lip c2, atthe outer end to engage the shoe-sole and at the opposite inner endprovided with a downturned threaded perforated lip c3.

al, is a bolt reversely threaded and centrally recessed at d2, andunthreaded. The bolt d, is provided with a square end d1, for detachab ysecurin turning the olt and thereby clamping the respective lips c2,firmly to the shoe-sole and toward each other on the threaded portionsof the bolt.

The foot being placed upon the plate c, of the skate A, by simplyturning the bolt d, in one direction the front portion is clamped to theboot or shoe by means of the lips c2, c2, and can then be loosened by areverse turningrr thereof, to release the boot from the late a, of theskate, when the ordinary hee and ankle holding straps are unbuckled.

e, is a depending bearing-support having a recessed end el, for spanninthe Unthreaded recessed portion d2, of the olt d, as clearly shown inFigs. 2 and 4.

Certain features as shown and described in the present application havebeen made the subject-matter of a separate agplication for a patentfiled by me under date ecember 2nd, 1908, under the Serial No. 405,706.

Having thus described the nature and objects of my invention, what Iclaim as new and desire to secure by Letters Patent is The combination,in a skate, of a foot plate a key thereto, not shown, for

having nont integral side depending slotted In witness whereof, l havehereunto sefJ guides, clamping-bars adapted to be slid in my signaturein the presence of two subscribthe slots of seid guides by meansconnected ing witnesses.

with said bars and seid means arranged so as WILLIAM J. HILLE. 5 to beadapted to look said bars in any given Witnesses:
